A graphical widget in a graphical user interface is an element of interaction, such as a button or a scroll bar. Controls are software components that a computer user interacts with through direct manipulation to read or edit information about an application. User interface libraries such as Windows Presentation Foundation, Qt, GTK, and Cocoa, contain a collection of controls and the logic to render these.
In computing, a mouseover, mouse hover or hover box is a graphical control element that is activated when the user moves or hovers the pointer over a trigger area, usually with a mouse, but also possible with a digital pen. Mouseover control elements are common in web browsers. For example, hovering over a hyperlink triggers the mouseover control element to display a URL on the status bar. Site designers can define their own mouseover events using JavaScript or Cascading Style Sheets.
State management refers to the management of the state of one or more user interface controls such as text fields, OK buttons, radio buttons, etc. in a graphical user interface. In this user interface programming technique, the state of one UI control depends on the state of other UI controls. For example, a state managed UI control such as a button will be in the enabled state when input fields have valid input values and the button will be in the disabled state when the input fields are empty or have invalid values. As applications grow, this can end up becoming one of the most complex problems in user interface development.
qooxdoo is an open-source Ajax web application framework. It is an LGPL- and/or EPL-licensed client-side and server-agnostic solution, and includes support for professional JavaScript development, a graphical user interface (GUI) toolkit and high-level client-server communication.
The Yahoo! User Interface Library (YUI) is a discontinued open-source JavaScript library for building richly interactive web applications using techniques such as Ajax, DHTML, and DOM scripting. YUI includes several core CSS resources. It is available under a BSD License. Development on YUI began in 2005 and Yahoo! properties such as My Yahoo! and the Yahoo! front page began using YUI in the summer of that year. YUI was released for public use in February 2006. It was actively developed by a core team of Yahoo! engineers.
This article details features of the Opera web browser.
UI data binding is a software design pattern to simplify development of GUI applications. UI data binding binds UI elements to an application domain model. Most frameworks employ the Observer pattern as the underlying binding mechanism. To work efficiently, UI data binding has to address input validation and data type mapping.
A single-page application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of a web browser loading entire new pages. The goal is faster transitions that make the website feel more like a native app.
AngularJS is a discontinued free and open-source JavaScript-based web framework for developing single-page applications. It was maintained mainly by Google and a community of individuals and corporations. It aimed to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures, along with components commonly used in web applications and progressive web applications.
Foundation is a free and open-source responsive front-end framework, providing a responsive grid and HTML and CSS UI components, templates, and code snippets, including typography, forms, buttons, navigation and other interface elements, as well as optional functionality provided by JavaScript extensions. Foundation is an open source project, and was formerly maintained by ZURB. Since 2019, Foundation has been maintained by volunteers.
A list builder, also known as a dual list, dual listbox, disjoint listbox, list shuttle, shuttle, swaplist, transfer list and two sided multi select is a graphical control element in which a user can select a set of text values by moving values between two list boxes, one representing selected values and the other representing unselected ones. Moving values back and forth is usually accomplished selecting values within one of the two lists and clicking buttons reading "Add" and "Remove", rather than by dragging and dropping them. Less traditionally, there may instead be an add or delete button individually next to each item. The widget can sometimes also include the ability to rearrange the selected values. There may also be buttons to add or remove all values, or a text field to filter the list.
Ember.js is an open-source JavaScript web framework that utilizes a component-service pattern. It allows developers to create scalable single-page web applications by incorporating common idioms, best practices, and patterns from other single-page-app ecosystem patterns into the framework.
There are different JavaScript charting libraries available. Below is a comparison of which features are available in each.
Material Design is a design language developed by Google in 2014. Expanding on the "cards" that debuted in Google Now, Material Design uses more grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows. Google announced Material Design on June 25, 2014, at the 2014 Google I/O conference.
React is a free and open-source front-end JavaScript library for building user interfaces based on UI components. It is maintained by Meta and a community of individual developers and companies. React can be used as a base in the development of single-page, mobile, or server-rendered applications with frameworks like Next.js. However, React is only concerned with state management and rendering that state to the DOM, so creating React applications usually requires the use of additional libraries for routing, as well as certain client-side functionality.
Ionic is a complete open-source SDK for hybrid mobile app development created by Max Lynch, Ben Sperry, and Adam Bradley of Drifty Co. in 2013. The original version was released in 2013 and built on top of AngularJS and Apache Cordova. However, the latest release was re-built as a set of Web Components, allowing the user to choose any user interface framework, such as Angular, React or Vue.js. It also allows the use of Ionic components with no user interface framework at all. Ionic provides tools and services for developing hybrid mobile, desktop, and progressive web apps based on modern web development technologies and practices, using Web technologies like CSS, HTML5, and Sass. In particular, mobile apps can be built with these Web technologies and then distributed through native app stores to be installed on devices by utilizing Cordova or Capacitor.
Polymer is an open-source JavaScript library for building web applications using Web Components. The library is being developed by Google developers and contributors on GitHub. Modern design principles are implemented as a separate project using Google's Material Design design principles.
jQWidgets is a software framework with widgets, themes, input validation, drag & drop plug-in, data adapters, built-in WAI-ARIA accessibility, internationalization and MVVM support. It is built on the open standards and technologies HTML5, CSS, JavaScript and jQuery. This library is used for developing responsive web and mobile applications. Some developers consider jQWidgets one of the top alternatives to the open-source jQuery UI.
Vue.js is an open-source model–view–viewmodel front end JavaScript framework for building user interfaces and single-page applications. It was created by Evan You, and is maintained by him and the rest of the active core team members.
Angular is a TypeScript-based free and open-source web application framework lead by the Angular Team at Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS.
